_________________________ADDITIONAL NOTES AND FINDINGS________________________


1) The Patch Test was performed on 02-28-2013.
2) The Multibeam data was collected on 04-19-2013.
3) Laser data is not submitted with this survey.
4) Due to a higher water surface elevation during the 2012 Revetment survey,
   there is a decrease in bankline coverage of approximately 5.5 feet.
5) There are sunken objects located at the following mileages/coordinates:
   *RM 207.0 - left bank (3321014.19,648758.13)
   
**The following note was established by a comparison of the 2013 Revetment
Bank to Bank Multibeam Survey to the 2012 Revetment Multibeam Survey**

6) There seems to be few areas of accretion and scour.
